Abstract (en)
[origin: US2005211571A1] The invention relates to a device for the electrochemical detection of at least one biochemical molecule-contained in a liquid-from a group of predetermined biochemical molecules, having a means ( 1 ) for taking up the liquid, said means having at least one reference electrode (RE) and at least one counterelectrode (GE) and also a multiplicity of working electrodes (AE 1 , AE 2 , AE 3 ), at least one working electrode (AE 1 , AE 2 , AE 3 ) being provided for the detection of each biochemical molecule, said working electrode being coated with a molecule that is complementary to the respective biochemical molecule, so that the biochemical molecules can be detected simultaneously, a potentiostat (P) for generating a predetermined voltage profile between the working electrodes (AE 1 , AE 2 , AE 3 ) and the reference electrode (RE), a current/voltage converter (S 1 , S 2 , S 3 ) being connected downstream of each of the working electrodes (AE 1 , AE 2 , AE 3 ), the current/voltage converters (S 1 , S 2 , S 3 ) holding all of the working electrodes (AE 1 , AE 2 , AE 3 ) at the same potential and a means (Ad) for measuring the currents flowing through the working electrodes (AE 1 , AE 2 , AE 3 ).
